Thomas & Betts 18RA-6F – Frequently Asked Questions

1) Does this fork terminal come for a #6 screw as well as a #10 stud?
Both stud sizes are offered in the RA Series fork terminal: order 18RA-10F for a #10 stud and 18RA-6F for a #6 stud. Same 22-16 AWG barrel either way, only the tongue spacing changes, so pick by the screw or stud diameter on the terminal block you are landing on.
2) What crimp tool do I need for Thomas & Betts RA Series terminals?
ERG4001 is the recommended tool. The RA Series also crimps with WT145C, WT2000, WT112M and ERG4003. A generic insulated-terminal crimper will close the barrel, but the serrated brazed seam only reaches its rated pull-out with the matched die.
3) Can I use these fork terminals in a 600V control panel running hot?
Rated 600V and 105 degrees C, so they are suitable for industrial control panels, motor control centers and distribution gear within those limits. The vinyl sleeve also carries a UL 94 V-0 flammability rating, and the terminals are UL and CSA certified and RoHS compliant.
4) What is the closest alternative to the Thomas & Betts RA Series insulated fork terminal if the RA series is not the one specified?
The 3M Highland vinyl-insulated block fork terminal is the comparable part. Both are vinyl-insulated fork (spade) terminals for stud connections. The Thomas & Betts RA terminal is copper with an electro tin-plated finish, rated 600V and 105 degrees C, with red vinyl insulation for 22-16 AWG wire and stud sizes of #6 or #10. If your spec calls out a fork terminal by function rather than by series, the Highland is a direct functional substitute; if the drawing names the RA series specifically, stay with the Thomas & Betts part.
5) Will this terminal fit over wire with thick insulation?
The insulation sleeve on the RA Series terminal accepts wire insulation up to 0.15 inch outside diameter. Standard THHN or appliance wire in 22-16 AWG falls under that; heavily jacketed or double-insulated leads may not seat fully into the sleeve, which costs you the strain relief the extra-long PVC barrel is there to provide.
6) Why choose a fork terminal instead of a ring terminal for panel work?
The open tongue on the RA Series fork terminal slides under a terminal screw that is only backed off, so you can add or pull a conductor without removing the screw entirely. A ring terminal is captive and cannot back out if the screw loosens, which is why ring style is the choice for vibration-prone equipment and automotive grounds. For terminal strips and control panels you service regularly, the fork is faster.
7) How many fork terminals come in a pack and can I buy fewer than 100?
They ship 100 to the inner pack and 500 to the outer carton, with an order multiple of 100. So quantities go up in hundreds, not singles.
8) Is a block fork terminal the same thing as the Thomas & Betts RA fork terminal?
They are both vinyl-insulated fork terminals, but the 3M Highland part is described as a block fork terminal, which refers to the tongue profile at the stud end. The Thomas & Betts RA Series is a standard fork tongue with an extra-long PVC insulation sleeve for stress relief at the wire flex point. If a panel has tightly spaced studs or crowded terminal blocks, confirm which tongue shape the terminal strip was built around before swapping one for the other.
9) If I am standardizing an MRO terminal kit across a facility, which of these two insulated fork terminals carries published ratings?
The Thomas & Betts RA Series fork terminal is the one with published electrical and material data: 600V, 105 degrees C, copper with an electro tin-plated finish, UL 94 V-0 flammability, and RoHS compliant, covering 22-16 AWG wire on #6 or #10 studs. The 3M Highland vinyl-insulated block fork terminal is the comparable fork terminal to stock alongside it where a 3M-standardized kit is already in place. For a facility spec sheet that has to state voltage and temperature limits, the RA Series gives you the numbers to write down.
10) Can I crimp a 3M Highland fork terminal with the same tool I use for Thomas & Betts RA terminals?
Do not assume so. The Thomas & Betts RA Series fork terminal calls for the ERG4001 as the recommended tool, with the WT145C, WT2000, WT112M and ERG4003 also listed as application tools. The 3M Highland vinyl-insulated block fork terminal is a separate series with its own crimp profile, so match each terminal to the die the manufacturer specifies for it rather than using one crimper across both brands.
11) Are these terminals copper or steel, and will they corrode in a damp mechanical room?
The RA Series terminal body is copper with an electro tin-plated finish, stock thickness 0.03 inch. Tin over copper gives you a corrosion-resistant contact surface that is compatible with copper conductors and the plated screws on most terminal blocks.
12) What is the alternative to a Thomas & Betts RA fork terminal if I need a different brand?
The 3M Highland vinyl-insulated block fork terminal is the other insulated fork style stocked here. It is the same connection method, so match the wire range and stud size to your application when you cross over, since the Highland listing is identified by series rather than by the RA barrel sizing.
